Consider the following class definitions. public class bclass { private int x; public void set(int a) { x = a; } public void print(){ } } public class dclass extends bclass { private int y; public void set(int a, int b) { //postcondition: x = a; y = b; } public void print(){ } } which of the following is the correct definition of the method set of the class dclass? (i) public void set(int a, int b) { super. set(a); y = b; } (ii) public void set(int a, int b) { x = a; y = b; }

Write a program that prints the day number of the year, given the date in the form month-day-year. for example, if the input is 1-1-2006, the day number is 1; if the input is 12-25-2006, the day number is 359. the program should check for a leap year. a year is a leap year if it is divisible by 4, but not divisible by 100. for example, 1992 and 2008 are divisible by 4, but not by 100. a year that is divisible by 100 is a leap year if it is also divisible by 400. for example, 1600 and 2000 are divisible by 400. however, 1800 is not a leap year because 1800 is not divisible by 400.
